FM Composite Multiplex over IP STL

Guest Speaker: David Agnew

This month's SBE meeting topic, Transport Robust and Secure FM Composite Multiplex Signals Over an IP STL, is brought to us by David Agnew of GatesAir.

The emergence of high bandwidth IP network connections is an enabler for the transport of the FM composite multiplex (MPX) signal in a Studio-to-Transmitter Link (STL). David will present use cases to illustrate differences between all analog, all digital, and dual domain FM MPX STLs and the tradeoffs they present with respect to compatibility and network bandwidth, scalability, and delay. They will also show how this IP based STL can be sent across legacy 950 MHz RF STL channels. Those who attended our February meeting know how this IP based STL can be sent across industrial microwave channels.

David Agnew is the Channel Manager of Intraplex Products with GatesAir in Mason, Ohio. Mr. Agnew is responsible for management of Intraplex product distribution channels in North America. David recently returned to Gates Air in January of 2017. He has 30 years of experience in AM and FM broadcast engineering starting in 1986 as a self-employed contract engineer, 12 years with Harris Corporation, in various positions including Radio Field Service and FM Applications Engineering, and the last 12 years as Director of Engineering with iHeart Radio in Lincoln, NE and Northern Colorado markets. Mr. Agnew has been an SBE member and Certified Professional Broadcast Engineer, holds an AAS degree in Electronics Engineering and continued education in Mathematics and Computer Science.

Brian Szewczyk, GatesAir's District Sales Manager for our region, will also be present to answer questions and provide a brief update on GatesAir's line of transmitter products.

Sandwiches, kindly provided by our friends at GatesAir will be served at 6:30 PM. We'll briefly discuss SBE business about 7:00 PM and begin our presentation shortly thereafter. Please RSVP before High Noon September 19th by dropping an e-mail to meet@sbe37.org and let us know if we should expect you for dinner!
